摘要:
针对油品泄漏火灾,设计并制备了4种不同组分的改性干水样品(DW),利用光学显微镜、激光粒度仪和热重分析仪进行表征分析,并搭建灭火实验平台,研究不同组分的DW对油品火灾的灭火效能。结果表明,制备的DW具备稳定的核壳结构,DW内部的含水量可达80%～90%,灭火组分和凝胶剂能够增大体积密度,有利于灭火剂到达火焰根部,提高灭火效能。灭火试验中,纯水DW1的灭火时间为49 s,加入草酸钾和凝胶剂的DW4的灭火时间为17 s,灭火时间减少了65.3%,充分发挥了物理和化学共同抑制燃烧的作用,有效缩短了灭火时间。研究结果对于干水灭火剂在石油化工领域的推广使用具有重要意义。
Abstract:
Four types of modified dry water samples(DW)with different components were developed and ready for use in oil leakage incidents. The fire extinguishing experiment platform was constructed to investigate the fire extinguishing effectiveness of several DW groups on oil fires. The characterization and analysis were performed using an optical microscope, a laser particle size analyzer, and a thermogravimetric analyzer. The findings demonstrate that the prepared DW has a robust core-shell structure and its interior water content can range from 80% to 90%. The volume density of the fire extinguishing agents and gels can be increased, which helps the agent reach the flame root more effectively and boost the efficacy of fire extinguishing. In the fire extinguishing test, the pure water DW1 fire is extinguished in 49 s, whereas the fire is extinguished in 17 s when DW4 is added with potassium oxalate and gel agent. This represents a 65.3% reduction in fire extinguishing time, fully utilizing the role of physical and chemical inhibition and significantly cutting down on fire extinguishing time. The findings have significant implications for the petrochemical industry's use of dry water extinguishing agents.
